Patented May 11, 1943 UNITED STATES TENT OFHC 1 Claim.

This invention relates to sanitary waste pail lining.

An object of this invention is to provide a lining which may be made ofinexpensive waterproof material, such as Cellophane, oiled or waxedpaper, or other paper, folded in a way that will make it collapsible, sothat the lining may be folded up compactly for shipping purposes.

A further object of this invention is to provide a lining of thecharacter described, provided with a rim at the top to catch over therim of the pail, and made a heavier paper than the body of the lining,and into which the body of the lining may be collapsed.

Still another object of this invention is to provide a lining of thecharacter described, having a corrugated body and a bottom of heavierpaper than the body of the lining.

Still a further object of this invention is to provide a neat anddurable lining of the character described, which shall be relativelyinexpensive to manufacture, easy to unfold, compact for the purpose ofshipment, sanitary in use, and practical and highly eificient.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts which will beexemplified in the construction hereinafter described, and of which thescope of the application will be indicated in the following claim.

In the accompanying drawing, in which is shown one of the variouspossible illustrative embodiments of this invention,

Fig. 1 is a vertical elevational View of a pail provided with a liningembodying the invention;

Fig. 2 is a top plan view of the lining in collapsed condition;

Fig. 3 is a cross-sectional view of the lining in collapsed condition;and

Fig. 4 is a partial, vertical cross-sectional View of the upper end ofthe lining, engaging the rim of the pail.

Referring now in detail, It] designates a pail provided with a lining Hembodying the invention. The pail H] has a bottom wall l2, a cylindricalwall l3 and a rolled upper rim M. The pail l may be provided with acover l5 of usual construction.

The lining H comprises a corrugated body which is collapsible to compactshape, as shown in Fig. 3 of the drawing. At the bottom of the body 20,is a bottom wall 22 preferably of heavier paper than the paper fromwhich the body 20 is made. The body 20 may be made of inexpensivewaterproof material, such as Cellophane, oiled or waxed paper, or anyother suitable sheet material.

Attached to the upper end of the body 20, is a rim 3!] made of heaviermaterial than the material of which the body 20 is made. Rim 30 isannular and comprises a central, downwardly skirted portion 3 I, fromwhich there extends outwardly a flange 32. Extending upwardly from theflange 32 is an inclined portion 33, from which there extends adownwardly curved portion 34. Extending from the downwardly curvedportion 35 is a downwardly extending cylindrical skirted portion 35.

The upper end 20a of the body 20, is pasted to the inner surface ofportions 33 and 34 of the rim 30. The portion 34 of the rim is adaptedto fit over the rim l4 of the pail, as illustrated in the drawing. Whenthe body is collapsed, it fits substantially wholly between the skirtedportions 31 and 35.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawing is to be interpreted as illustrative and not in alimiting sense.

Furthermore, although the device H has been described as a liner forpails or cans, it will be understood that the same may be used as areceptacle or for the like purposes.

It will be noted that the body 20 of the article H is constructed like abellows, so that the body may be collapsed in compact form, as shown inFig. 3 of the drawing.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

A liner for a pail comprising an annular rim member adapted to engagethe open end of a pail, said rim member having a downwardly extendingcylindrical wall adapted to be received within the pail, a horizontalflange extending outwardly therefrom, an upwardly and outwardly annulartapered portion extending from said flange, an annular downwardly curvedportion extending from said tapered portion and adapted to engage theupper rim edge of the pail, a downwardly extending, annular, skirtedwall extending from said curved portion and adapted to be disposedoutside of said pail, an annular bellows like collapsible body, theupper end of said body being received within said rim member andattached to the inner surfaces of said tapered and curved portions ofsaid rim member, and a'bottom wall attached to the bottom of saidbellows body.
